CAPE (Comprehensive AI Privacy Extension) is a free browser add-on designed to enhance privacy during interactions with AI platforms like ChatGPT and GitHub Copilot. This extension provides real-time detection and pseudonymization of sensitive data, ensuring that personal and professional information remains confidential while using various AI tools. By utilizing a zero-trust architecture, CAPE does not store raw input data, thereby safeguarding user privacy effectively.

Key features include AI-driven detection of personally identifiable information (PII), automatic redaction of sensitive text, and seamless integration with Azure AI Language Services. CAPE is particularly beneficial for software developers, security-conscious teams, and enterprise organizations that operate within regulated industries. Its interactive audit interface allows users to visualize risk categories and token mappings, providing an added layer of security and control over data handling.
